What Is White Noise And How White Noise Machine Can Help You Sleep

We all don't get the sleep we need. Why is that? Things like work, stress, or just having difficulty winding down before bedtime are just a few reasons why people have trouble sleeping.

Countless studies on sleep quality have shown that adequate sleep results in better overall health, a better sex life, lower risk of injury, and better mood to name a few benefits.

Inadequate rest can cause a plethora of issues, such as decreased productivity, inability to focus, bad mood, weight gain, and the chance to develop chronic illnesses such as diabetes, high blood pressure, heart disease, and more.

I'm a40 year old father of two young children (age 6 and 4), and I'm married, so trust me when I say that I know how important sleep is! I'm also a snorer and a sufferer of mild sleep apnea, which keeps me and my family awake at night.

I've just recently moved to the countryside. I used to live in a flat where I could hear everything my neighbors were doing, particularly their TV and the occasional dog barking at night. This is when I began to experiment with white noise for sleeping issues.

What Is White Noise?

White noise is commonly heard when your TV has no reception, or when your radio has no signal. Click the play button below to hear it, or if you've ever wondered what does white noise sound like. The term "white noise" can be used in various contexts, from signal processing to discrete time, butwhite noise will pertain to audio in this article, its most common context.

To understand what white noise is, look at the name. The term gets its name from 'white light', which is all colors, or the frequency of all colors, combined. White noise is a combination of all the frequencies of sound you can hear.

For a more precise definition, white noise is the frequency created when all different frequencies of audible sound that the human ear can perceive are put together at a similar level. The frequencies we hear are between 20 - 20,000 Hertz.

A good example is when you're waiting for a game to start in a sports stadium. Thousands of people are talking, and it sounds like a blurred roar. White noise has a similar effect. Hearing so many different tones at the same time blurs into a hissing or hushing sound.

This is why the sound of rain, wind, waterfalls, and oceans are included on white noise machines. They're similar to white noise due to various tones. White noise is used to drown out any outside noises in the environment.

It creates a "masking effect", which blocks out sudden changes that disturb light sleepers or those that are trying to fall asleep.

You now know what white noise is and what it's used for, but what do you know about white noise machines?

What Is A White Noise Machine?

A white noise machine is a device that produces random sounds, like rushing water, wind blowing through the leaves of a tree, ocean waves, or the sounds of traffic.

These devices usually do not produce actual white noise (which has a harsh sound), but pink noise, which uses the frequencies of other colors to produce softer sound. These machines can also produce brown noise, which is like pink noise except even softer.
